[QUOTE="2004cobra615, post: 16009829, member: 84735"] So I have some questions. Looking to make 700 plus RWHp but gain lOW end torque... If can out of the 2.9 whip. I have heard it shines at around 25 Ilbs or higher. It's a stock motor so I don't want to go crazy or swtich everything on the car. What's the best combo to reach 25ish ilbs boost with my 2.9 Whipple running e 85? I have a accufab single blade TB, jlt ram carbon fiber intake and standard inlet 2.9 Whipple second gen. JBA shorthy headers 80ilb deka injectors and lethal budget return. I'm in Illinois so air isn't to thin. Will a 3 inch upper make to 25 ilbs alone. If i throw a 3 inch pulley on the Whipple will I have belt slip.... is that why the lower comes in handy here? My 3.5 pulley I have no issues with slip I would prefer to keep stock lower but is there a huge benefit to changing it besides risking my crank snout. From what I have read I think a 3 inch upper with stock lower should be 23 to 25 Ilbs correct... Other advice for increasing the low end torque/hp? anyone with this set up can you chime in. Help is much appreciated. 2004 Cobra 2.9 Whipple [/QUOTE]
